Application filed February 14, 1921.

1' '0 all whom it may concern 7 Be it known that I, Mounts Ionnonorr, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators such as are used on automobiles for the purpose of cooling the water passing through the circulatory system of the engine, and has for its object the provision of a radiator in which the cooling tubes are formed in groups, any group being removable without in any way affecting the other group, the great advantage of the device being that in case of damage to the radiator, the damaged section or group may be removed and re placed. without in any way affecting the others.

An important and most specific object is the provision of a radiator of this character in which there is provided a series of vertically arranged tubes disposed between the upper and lower tanks of the radiator, the tubes communicating with the interiors of pan like heads which have a dove-tailed connection with the upper and lower tanks.

an additional object is the provision of a radiator of this character which will be simple and inexpensive in construction, easy in assembling highly eflicient in use, durable in service and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which Figure l is a front elevation of a radiator constructed in accordance with my invention.

Fig. 2 is a side elevation thereof with portions broken away and in section.

Fig 3 is a perspective view of one of the pan like heads showing one side thereof.

Fig. 4: is a perspectlve view showing the reverse side thereof, and

Fig. 5 is a fragmentary perspective view of one end of the bottom closure plate of the upper tank or the top closure plate of the lower tank.

Referring more particularly to the drawings Ihave shown my radiator as compris- Specification of Letters Patent.

in upper and lower tanks 10 and 11 respectively, the former of which is provided with the usual filling neck 12. The bottom of the upper tank 10 and the top of the lower tank 11 are closed by plates 13 and 1% respectively which are formed on their confronting faces with dove-tailed grooves 15 which are similar. tanks are connected by side members 16 constituting a species of frame which are preferably webbed as shown at 17 for the purpose of providing great strength.

The numeral 18 designates a series of vertically disposed cooling tubes which extend between the upper and lower tanks and these tubes are arranged in groups or sections as clearly shown in Fig. 1. At its upper and lower ends each group of tubes carries and communicates with pan shaped heads 19 clearly disclosed in Figs. 3 and Al of the drawings. These pan heads are formed with dove-tailed projections 20 slidably fitted within the dove-tailed grooves 15. Likewise associated with and extending through one end of the heads 19 are tubes 21 having their ends within the heads beveled and cutaway as indicated at 22 and formed adjacent their outer ends with holes 23. These tubes 21 are disposable through holes formed in extensions 2% in the closure plates 13 and 1e and have their extremities threaded and provided with closure caps 25.

The extensions 24; on the plates 13 and 14 extend longitudinally of the plate and are formed with a plurality of spaced openings 26 which establish communication with the respective tanksas clearly shown in Figs. 2 and 5. Certain of the portions of the extensions 24: are formed with holes 27 for the passage of the tubes 21as will be readily apparent.

In actual practice the various vertical tubes 18 may be provided with any suitable cooling portions, though in the present instance I have shown them as formed with spirally arranged cooling ribs 28.

In the assembling of my radiator the various groups or sections of tubes are in serted by engaging the upper and lower pan like heads 19 within the corresponding dove-tailed grooves 15 in the plates 13 and 1% respectively with the tubes 21' passing through the registering holes 27 in the extensions 2e. The caps 25 are then screwed onto the threaded ends of the tubes 21 The upper and lower From the foregoing and a study of the drawings it will be apparent that I have thus provided a very simply constructed and consequently inexpensive radiator in which the tubes are arranged in sections,

any of the sections being easily and quickly removable without disturbing any of the other sections. It is thus to be observed that the radiator is particularly advantageous in cases of accident such as damage in a collision or in case of breaking inasmuch as the removal and replacement of one group of tubes may be eflected without interfering with the other group or section.

While I have shown and, described the preferred embodiment of the invention, it is of course to be readily understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention I claim:

1. A radiator comprising upper and lower tanks, the upper and lower tanks being closed at their lower and upper surfaces respectively by means of plates formed with hollow extensions communicating with the tanks, said plates being formed in their confronting faces with grooves, a series of vertically disposed tubes disposed between said tanks, pan-like heads carried by and communicating with the upper and lower ends of said tubes and formed with extensions fitting within said grooves, extensions formed on said plates and provided with openings communicating with the respective tanks, said last named extensions being provided in registration with said grooves with openings and tubes carried by said pan-like heads passing through said openings and carrying retaining caps. V

2. A radiator comprising upper and lower tanks, plates forming closures for the lower and upper surfaces of said upper and lower tanks respectively, said plates being formed with dovetailed grooves and being formed 011 their confronting faces with extensions formed hollow and communicating with the interiors of the tanks, a plurality of vertically disposed tubes arranged between said tanks, heads closing and communicating with the interiors of the tubes and dividing the same into groups, said heads being formed with dove-tailed tongue members fitting within said grooves, tubes carried by and communicating with the interiors of said heads and passing through the hollow extensions on said plates, caps secured on the free ends of said tubes whereby to prevent dislocation of the heads, and said tubes being formed with holes communicating with the interiors of said first named extensions.

A radiator comprising upper and lower tanks, plates forming closures for the lower and upper sides of said. upper and lower tanks respectively, said plates being formed in their respective faces with dove-tailed grooves, a series of vertically disposed tubes arranged between said tanks, heads carried by and communicating with the upper and lower ends of said tubes, said heads being formed with clove-tailed extensions slidably engaged within said grooves, tubes carried by and communicating with the interiors of said heads, extensions on the plates provided with openings communicating with the tanks, said extensions being formed in registration with said grooves with holes, tubes carried by and communicating with said heads and passing through said holes, said tubes being formed with holes communicating with the interiors of the extensions, and caps screwed upon the free ends of said tubes whereby to prevent displacement of the groups of tubes.

In testimony whereof I afiix my signature,

MORRIS POLNOROFF.
